Forgive my ignorance, but how does that following not meet your spec? Obviously I haven't included long characters in the test, but I would like to understand what the trip-ups are for my own education. 

#!/usr/bin/perl -w
use strict;

require HTML::TreeBuilder;

my $tree = HTML::TreeBuilder->new; # empty tree
$tree->parse($_) while <DATA>;
$tree->eof;
$tree->elementify();

# Looking for
# <meta http-equiv=Content-Type content="text/html; charset=windows-12
+52">
my $content_type = $tree->look_down(
    '_tag', 'meta',
    sub {
        my $elem = shift;
        $elem->attr('http-equiv') eq 'Content-Type';
    }
    );

print $content_type->attr('content'), "\n";
